physical external interface mapping always get tagged interface setting

[myf5]

Set physical mapping as :
f5_external_physical_mappings = default:1.1:False,vlannet:1.2:False

Found the vlan created for "vlannet" always be tagged interface. This was found when test openstack lbaas v1. Found the issue was caused by permanent true logic in the below code. After checking V2 code, seem like same logic issue.

` def _assure_device_network_vlan(self, network, bigip, network_folder):
# Ensure bigip has configured tagged vlan
# VLAN names are limited to 64 characters including
# the folder name, so we name them foolish things.
vlan_name = ""
interface = self.interface_mapping['default']
tagged = self.tagging_mapping['default']

    # Do we have host specific mappings?
    net_key = network['provider:physical_network']
    if net_key and net_key + ':' + bigip.hostname in \
            self.interface_mapping:
        interface = self.interface_mapping[
            net_key + ':' + bigip.hostname]
        tagged = self.tagging_mapping[
            net_key + ':' + bigip.hostname]
    # Do we have a mapping for this network
    elif net_key and net_key in self.interface_mapping:
        interface = self.interface_mapping[net_key]
        tagged = self.tagging_mapping[net_key]

    if tagged: <<<<<<<<<<<!!!!!!!!
        vlanid = network['provider:segmentation_id']
    else:
        vlanid = 0`
